This US National Intelligence Council memo dated 14 September 2011 provides US talking points for a forthcoming NATO meeting and includes the assessment that the threat presented by Anonymous and hacktivist activity is “minimal”: see the Intercept article Western Spy Agencies Secretly Rely on Hackers for Intel and Expertise, 4 February 2015.

This document lists the 193 governments, intragovernmental organisations and other entities which the NSA was granted the legal authority to intercept communications “about” for foreign intelligence purposes in August 2010: see the Washington Post article Court gave NSA broad leeway in surveillance, 30 June 2014.

The NSA's Foreign Affairs Directorate approved exploratory talks with new NATO member country Estonia on a possible signals intelligence relationship. An Air Force information operations group “was very interested in an exchange,” and the military believes Estonian forces are monitoring signals intelligence related to nearby Russian air and ground operations.
